</code></pre></div><p>同样地，这在 <code>*.vue</code> 文件的模板中一样可以工作，图片将会被 <code>url-loader</code> 和 <code>file-loader</code> 处理，在运行生成静态文件的构建任务时，文件会被复制到正确的位置。</p> <p>除此之外，你也使用 <code>~</code> 前缀来明确地指出这是一个 webpack 的模块请求，这将允许你通过 webpack 别名来引用文件或者 npm 的依赖：</p> <div class="language-md extra-class"><pre class="language-md"><code><span class="token url">![<span class="token content">Image from alias</span>](~@alias/image.png)</span>
<span class="token url">![<span class="token content">Image from dependency</span>](~some-dependency/image.png)</span>
</code></pre></div><p>Webpack 的别名可以通过 <code>.vuepress/config.js</code> 中 <a href="/vuepress-theme-purple/zh/config/#configurewebpack">configureWebpack</a> 来配置，如：</p> <div class="language-js extra-class"><pre class="language-js"><code>module<span class="token punctuation">.</span>exports <span class="token operator">=</span> <span class="token punctuation">{</span>

</code></pre></div><h2 id="公共文件"><a href="#公共文件" class="header-anchor">#</a> 公共文件</h2> <p>有时，你可能需要提供一个静态资源，但是它们并不直接被你的任何一个 markdown 文件或者主题组件引用 —— 举例来说，favicons 和 PWA 的图标，在这种情形下，你可以将它们放在 <code>.vuepress/public</code> 中， 它们最终会被复制到生成的静态文件夹中。</p> <h2 id="基础路径"><a href="#基础路径" class="header-anchor">#</a> 基础路径</h2> <p>如果你的网站会被部署到一个<strong>非根路径</strong>，你将需要在 <code>.vuepress/config.js</code> 中设置 <code>base</code>，举例来说，如果你打算将你的网站部署到 <code>https://foo.github.io/bar/</code>，那么 <code>base</code> 的值就应该被设置为 <code>&quot;/bar/&quot;</code> (应当总是以斜杠开始，并以斜杠结束)。</p> <p>有了基础路径（Base URL），如果你希望引用一张放在 <code>.vuepress/public</code> 中的图片，你需要使用这样路径：<code>/bar/image.png</code>，然而，一旦某一天你决定去修改 <code>base</code>，这样的路径引用将会显得异常脆弱。为了解决这个问题，VuePress 提供了内置的一个 helper <code>$withBase</code>（它被注入到了 Vue 的原型上），可以帮助你生成正确的路径：</p> <div class="language-vue extra-class"><pre class="language-vue"><code><span class="token tag"><span class="token tag"><span class="token punctuation">&lt;</span>img</span> <span class="token attr-name">:src</span><span class="token attr-value"><span class="token punctuation">=</span><span class="token punctuation">&quot;</span>$withBase('/foo.png')<span class="token punctuation">&quot;</span></span> <span class="token attr-name">alt</span><span class="token attr-value"><span class="token punctuation">=</span><span class="token punctuation">&quot;</span>foo<span class="token punctuation">&quot;</span></span><span class="token punctuation">&gt;</span></span>
</code></pre></div><p>值得一提的是，你不仅可以在你的 Vue 组件中使用上述的语法，在 Markdown 文件中亦是如此。</p> <p>最后补充一句，一个 <code>base</code> 路径一旦被设置，它将会自动地作为前缀插入到 <code>.vuepress/config.js</code> 中所有以 <code>/</code> 开始的资源路径中。</p></div> <footer class="page-edit"><div class="edit-link"><a href="https://github.com/fengxinming/vuepress-theme-purple/edit/master/zh/guide/assets.md" target="_blank" rel="noopener noreferrer">在 GitHub 上编辑此页</a> <svg xmlns="http://www.w3.org/2000/svg" aria-hidden="true" x="0px" y="0px" viewBox="0 0 100 100" width="15" height="15" class="icon outbound"><path fill="currentColor" d="M18.8,85.1h56l0,0c2.2,0,4-1.8,4-4v-32h-8v28h-48v-48h28v-8h-32l0,0c-2.2,0-4,1.8-4,4v56C14.8,83.3,16.6,85.1,18.8,85.1z"></path> <polygon fill="currentColor" points="45.7,48.7 51.3,54.3 77.2,28.5 77.2,37.2 85.2,37.2 85.2,14.9 62.8,14.9 62.8,22.9 71.5,22.9"></polygon></svg></div> <div class="last-updated"><span class="prefix">上次更新:</span> <span class="time">2020-1-13 1:59:37</span></div></footer> <div class="page-nav"><p class="inner"><span class="prev">
